She said: "We believe the incident occurred at the junction between Everingham Road, Acacia Road and Green Boulevard but it could have been further up Green Boulevard as he doesn't remember it happening and this is the route he takes home. He doesn't even remember ringing me for help.

"He has suffered extensive injuries including fractures to his skull, cheekbone, eye socket and a bleed on the brain. He now needs major surgery.

"Any information would be much appreciated, doesn't matter how small.

"If anybody knows of any local residents' with CCTV please get in touch. Please contact me or the police as they are currently investigating the incident."
